Unchecked_Conversion help needed

["rcarnesiii" <reid_carnes@yahoo.com>]

I used Ada many years ago and am now getting back into it. Here's my
problem, I have to applications and am sending messages between them.

Sending procedures function call
Send_Message
     (Partner => The_Handle,
      Message => Message(X)'Address,
      Bytes   => Message(X).Length,
      Message_Id => My_Message_Id);

On the receiving side my callback routine looks like this

Process_Message_From_Partner
            (Partner : Xxx.The_Handle;
             Message : in System.Address;
             Bytes   : in Positive;
             Message_Id : in Xxx.Message_Id) is

begin
  my code

end Process_Message_From_Partner;

What I would like to do is print out the message on the receiving side.

Is this possible using unchecked_conversion ?

Thanks
